摘要:
A surgical instrument for cutting a tissue and related methods includes a shaft, a cutting member, and an axial adjustment coupling. The shaft and the cutting member are configured to articulate from a first configuration toward a second configuration and respectively have distal and proximal shaft ends distal and proximal member ends. The cutting member is disposed within the shaft and configured to cyclically move relative to the shaft. The axial adjustment coupling is configured to longitudinally move the proximal member end relative to the proximal shaft end while articulating the shaft and the cutting member from the first configuration toward the second configuration. Thereby, the axial adjustment coupling inhibits movement of the distal member end relative to the distal shaft end for maintaining alignment between a shaft window opening in the shaft and a cutting window opening in the cutting member.
